Anna Brown was an artist who believed that it was important to help others. When she heard of a summer camp for children with serious illnesses, she came up with an idea. It cost money for these kids to go to the camp, so Anna decided to see what she could do to help. It was impossible for her to donate (捐赠) a lot of money, so she had to think of another way.

She wanted to take advantage of her love of art. So she started making and selling beautiful cards to raise money for these kids. Because these cards were all handmade, it would take her a long time to make a lot of them. So Anna had another idea. She started inviting friends to her house to help her make the cards. At first her friends were hesitant. Many said that they were not artistic and didn’t know how to make cards. But once they saw the beautiful materials that she had in her workroom, her friends felt more comfortable doing things such as drawing and cutting in order to make a new card.

But the materials were expensive. To make money without spending money, Anna asked for and got donations of paper, glue, scissors, and other things from nearby stores. She sold her cards for three dollars each in different art markets during the year. Anna raised more than $30,000 in her 10 years making cards.

On the afternoon of March 23, 2022, Chinese astronauts on board China’s Tiangong space station gave a science lesson 400 kilometers above Earth. It was a great success. Do you still remember the first space lesson hosted by Wang Yaping in 2013? Helped by the other two astronauts, she gave the lesson to more than 60 million school children all over the country.

While watching the science lesson from the Tiangong-1 on the morning of June 20, 2013, Wang Lutian, a 10-year-old disabled student at a special school in downtown Beijing, was drawing a colorful rocket with crayons in his classroom. “Moon…stars…a rocket to the sky,” Wang explained his work in a cheerful voice. At that time, he and more than 100 other disabled students were enjoying the lesson given by Wang Yaping, who talked about movements in micro-gravity（微重力）environments. “Zero gravity!” Qian Shaohong, another student at the school, shouted when he saw astronaut Nie Haisheng making a show of crossing his legs in mid-air. “Scientific knowledge has helped open a window for the children to know about the world,” said Zhang Yini, a teacher at the school.

The lesson also increased interest in space science among teenagers living on the “roof (屋脊) of the world”. “I was most interested in the presentation of the ‘water ball’ in a gravity-free environment. It’s really amazing,” said Rigzin Jigme Doje, a high school student in Lhasa, Tibet. Describing himself as a lover of physics, Doje said the lesson helped him stay true to his dream of becoming a physicist.

The lesson also encouraged other Tibetan school children to relate the mysterious world of outer space to their hometown.

Success is often considered to be the opposite of failure. To teenagers, it is the achievement of a goal or completion of something they really need, such as good grades and the ability to get along well with their classmates. Some schools used to agree with most parents who measured (判定) the success of their children according to grades, but now they pay special attention to moral (道德的) education and character-building to make sure teenagers achieve success in building human relationships.

Schools give chances to students to discover their hidden ability so that they can enjoy some form of success. For example, those good at speaking skills are advised to take part in speech competitions while those interested in arts are expected to perform in front of their classmates. Teenagers also get the pleasure of success when they join their favorite clubs.

Teenagers are often told that success is not easy to achieve and that success lies in hard work. Great efforts have to be put into project work. Doing things much later than planned should be avoided as this will lead to a mountain of work which finally makes them nervous. Another good quality (品质) is a sense of responsibility which makes them remember that a task has to be completed.

Sticking to moral values is the key to success too. Honest teenagers will win the trust of friends leading to good relationships. Self-motivation (自我激励) is another quality to be developed, for self-motivated teenagers will have the strong will and drive to perform a task and finally get to enjoy a sense of achievement.

Cyclists need to be more careful than other road users, as it’s much easier for you to get hurt. Remember that when you are on a cycle, you have no protection from dangers around you.     46    

Don’t use your mobile phone while cycling. This is because you need to look out for the road and other traffic.

You should always wear a helmet as this can cut down the risk of getting hurt on the head in an accident.

Do not change your direction suddenly.     47     Always look carefully before you start, stop or turn. Let drivers know you have seen them.

    48     If not, why not? Brakes must work well in all conditions: dry and wet. Are the tyres in good condition to make sure of the safety of your trip?

Traffic laws apply (适用) to you as a cyclist, as well as other road users.     49     It is against the law for them to take the following actions.

●Jump red lights, including lights at pedestrian (行人) crossings, unless there’s a sign showing that cyclists are allowed to do this.

●     50    

●Cycle the wrong way up a one-way street, unless there’s a sign showing that cyclists can do so.

In the closing years of the Sui Dynasty, a terrible flood (洪水) happened on the Xiao River outside the city of Zhaozhou.     61     flood brought down a large stone bridge.

People had rebuilt the bridge many     62     (time). But it was still washed away over and over again. “What’s wrong     63     it?” Li Chun, the most famous local engineer at that time, asked himself. He     64     (work) day and night at the drawing of the bridge and found out that the stone supports (支柱) couldn’t stand the force of the flood.

One day, an idea came into his mind! He thought of     65     (build) bow-shaped arches (拱) instead of stone supports. And there would be only one big arch, supported at each end by two small ones. When floods came, the waters would run through the     66     /fɔ: (r)/ small arches, bringing little influence on the bridge. He was     67     (great) excited by the idea, and danced happily right at his desk.

A new Zhaozhou Bridge was built. It was safe     68     beautiful. The local people of Zhaozhou were very     69     /glæd/ that the problem of the stone bridge was finally worked out. Now, this great stone bridge with a history of over 1,300 years has     70     /bɪˊkʌm/ a classical example of China’s arched bridges. It shows the wisdom and creativity of the Chinese people.
